Application led Detober 11, 1927. Serial No. 225,431.l

rlhis invention relates Vto a block tablel plane and has for one of its objects the provision of means for resurfacing a block` table such as that used by tailors or ofthe vtype used by butchers.

Another objectv of our invention is the provision ofV a bloclrplane that can be conveniently transported and easily applied to tables of all sizes.

A furtherobject of our invention 1s the provision of a plane of the class described comprising a rotary saw blade adapted to form a horizontal incision below the surface of a block table and a cutting ineinbei' mounted thereon adapted to cut or gauge away the material between the old rsurface of the table and the incision thereinV for providing a new surface.

` A still further object of our invention is` novel features and combinations being more i clearly set forth in the appended claims.

Vmounted. .The body of the plane comprises a cast iion'base portion 11 having a machined lower horizontal surface 12 whichis adalited` to upon the old or used earface of the table block. motor 13 is mounted on the top Vportion 14e ofthe base 11 and is secured thereto by bolts 15. rEhe shaft 16 of the motor is provided with a thrust bearing 417 and is rigidly attached to a bevel gear 18 disposed inadvance of the base of the plane as shown in Figs. 2 and 3,l A fan member 19 issecured to the shaft 16 for cooling the armature of the motor. j y

f The front side of the base l1 is provided with a handle 2O and the rear side 21 is provided with spaced brackets 22-and 23 and 'with a handle member 24. An extensible Y shaft comprising' an upper section 25, a lower section 26 and an intermediate sleeve 27 is journaled in apertures in the brackets 22 and 23. The upper section 25 is .provided with a bevel gear 28 whichis Vmeshed with the `bevel gear 18 ofthe motor shaft and the shaft section 25 is supported by a thrust bearing V29. The sleeve 27 is rigidly attached to the lower extremity of the upper shaft section 25y and is adapted to receive the upper end portion of the lower shaftsection 26. rlhere are a plurality of apertures in t-he shaft section 26 adapted to register with apertures inthe sleeve 27 for receiving` a pin 30 by means of which the shaft section 26 may be securedtothe sleeve 27 as desired. llt should be understood that the shaft coinprising sections 25 and 26 and sleeve 27 is substantially vertical and that the saine is adapted vto be extended and made rigid by inserting the pin 3Q in any registering apertures in the sleeve and section'26. It should also be understood that the shaft is rotated by the motor n 13 through the bevel gears 18 and 28; l

. The-lower extremity of the shaftsection 26 Ais'provided with a foot 31 which is rigidly secured thereto. A disosaw blade 32 is rigidly mounted on the bottoni of the foot 31 by bolts, or the like, 83. A toolso'clret` 84C is `pivotally mounted on the foot 31 by a bolt A 35 and is adapted to hold 4a cutting' member 36.-' The soclret-ainay be secured ina radial position or at an inclination to the radii of the foot 31 as desired and it is provided with a set screw 37 by means ofwhich the'cutting :lrnembere 66 may be held in extended; or
